Four methods were employed to isolate ADH from Acetobacter Z127 just to find bacteriolytic solution could break cell efficiently and maintain ADH activity simultaneously and thus it was suitable for the extraction of Acetobacter Z127 ADH.

• 用4种不同的方法提取ADH,结果发现细菌裂解液提取法对Acetobacter Z127细胞的破碎率较高,而且能够维持较高的ADH活性,较适合Acetobacter Z127中ADH的提取。
